How did David get into acting?

From the age of three he wanted to become an actor due to his love of Doctor Who, which he would watch religiously.

He acted in school productions and he was spotted at a young age by Scottish actress Edith MacArthur, who is best known for her role as Lady Laird Elizabeth Cunningham in Scottish soap opera Take the High Road.

David attended weekend classes at the Royal Scottish Academy of Music and Drama before passing an audition for the school at the age of 16. He studied there full-time until he was 20.

There was already a David McDonald on the books, so David started going by Tennant after reading about Pet Shop Boys frontman Neil Tennant in a copy of Smash Hits. He later had to change his name legally to meet Screen Actors Guild rules.
